[Japan Meteorological Agency 3-month forecast] Extremely hot weather this summer too...Be careful of heavy rain during the rainy season


2024/05/21 22:10

TOPICS IMG

Today, the 21st (Tuesday), the Japan Meteorological Agency announced a ``3-month forecast'' that summarizes the weather outlook for this summer (June to August).

Due to global warming and the effects of the El Nino phenomenon until spring, the temperature of the entire atmosphere is expected to rise considerably across the globe.

In the tropical Indian Ocean, sea surface temperatures will be high, especially in the western part, and cumulonimbus clouds will be more likely to form.

On the other hand, it is likely to be less in the sea east of the Philippines.

As a result of this, the Pacific anticyclone is expected to be strong in the south of Japan.
It is expected that warm, humid air will flow around the edge of the Pacific anticyclone around Japan.

As a result, the area around Japan will be
more likely to be covered with warm air, so it will be a very hot summer with high temperatures across the country.

Also, western Japan and Okinawa/Amami will be more susceptible to the effects of fronts and humid air.
We will need to be careful about heavy rain during the rainy season.

The Pacific side of eastern Japan and the Sea of Japan side of western Japan have many cloudy and rainy days, similar to normal years.

The Pacific side of western Japan and Okinawa/Amami are susceptible to fronts and humid air, so
there are more cloudy and rainy days than normal.

*July
On the Sea of Japan side of northern and eastern Japan, there are many cloudy and rainy days,
like normal years.

The Pacific side of eastern Japan and western Japan are susceptible to the effects of fronts and humid air during the first half of the
period, so there are more cloudy and rainy days than normal. The second half of the
period will have many sunny days, similar to normal years.

Okinawa and Amami are easily covered by high pressure, so
there are more sunny days than normal.

*August

In northern Japan, the weather changes every few days.

Eastern and western Japan and Okinawa and Amami have many sunny days, similar to normal years.

High temperature + humidity = hot and humid. Even rain increases the risk of heat stroke. Early weather information regarding high temperatures


2024/05/20 16:20

TOPICS IMG

Today, the 20th, the Japan Meteorological Agency announced ``early weather information regarding high temperatures'' for southern Kyushu, Amami, and Okinawa regions.

From now on, warm air is expected to flow from southern Kyushu to the Nansei Islands,
and there will be many days with high temperatures,
especially from around the 26th, there is a possibility that temperatures will be ``significantly higher'' than normal.

Please be careful about managing crops and livestock.

Southern Kyushu~ If you look at the
weather mark in the weekly forecast for the Nansei Islands, it will mostly be rain.

We tend to think that heatstroke occurs when the weather is sunny and the temperature rises, but
the number of people suffering from heatstroke increases rapidly during rainy, humid seasons.

This week, in addition to high temperatures, rain will increase humidity and make it even more humid, so we need to be even more careful about heat stroke than
.

Even if the temperature does not reach 30c, on a hot, humid day with rain,
please take good care of your health to prevent heat stroke.

In addition, 1 If high temperatures are predicted within a week, we will send you weather information regarding high temperatures,
If weather conditions that pose an extremely high risk of heat stroke are expected the next day or on the same day, we will send you a heat stroke warning alert. It will be announced.

With hazard map Be sure to check evacuation sites and evacuation routes.
When a disaster occurs due to heavy rain,
evacuation routes may be impassable or evacuation sites may not be accessible.
Avoid choosing evacuation routes to areas with a high risk of flooding or landslides.


Be sure to prepare and check your emergency supplies.
It's a good idea to prepare water, food, spare batteries, and a water tank in case of power outages or water outages.

Also, be sure to thoroughly clean the gutters and other areas where fallen leaves and gravel have accumulated.
By ensuring good drainage, even in the event of heavy rain, drainage will occur smoothly and the flooding of roads can be reduced.

If it rains heavily, you may not be able to prepare or clean in time, so
be sure to prepare for the heavy rain before it starts.
